Fixes#3875
* Use .json files (instead of .tid) for any tiddler whose fields contain values that can't be stored as a .tid file
* Save application/json tiddlers as .json files
* Refactor most of the file handling as re-usable utilities
First part of fix for #3875
The idea is to do a better of job of distinguishing JSON files that contain tiddlers versus those that contain plain blobs of JSON that should be stored as a single application/json tiddler.
Under Node.js, .json files with an accompanying metafile are always treated as a JSON blob. Without a meta file, those that appear to not contain valid tiddlers are returned as a JSON blob, otherwise the tiddlers within the file are imported.
In the browser, we don't have .meta files so we rely on the valid tiddler check.
If the path was not specified, RSOD error occurred when we wanted to
download the wiki:
Uncaught TypeError: Cannot read property 'substring' of undefined
* Update TiddlyWiki5 Squared by Iannis Zannos.tid
Link no longer works. Changed it to the github page.
* Update TiddlyWiki5 Squared by Iannis Zannos.tid
Fixed URL linking to the "ur" field
Changed line
`<<toc-selective-expandable "TableOfContents" "sort{fuzzy}">>`
to
`<<toc-selective-expandable "TableOfContents" "sort{!!fuzzy}">>`
Tested that this is the correct code.
* Add uniquetitle macro
This macro is a wrapper on the $tw.wiki.generateNewTitle function to return a unique name, it has been requested multiple times in the forums.
* Add documentation tiddler for uniquetitle macro
* Add uniquetitle macro examples
* Change name from uniquetitle to unusedtitle for clarity
The title isn't unique, just not currently used in the wiki.
* Update uniquetitle to unusedtitle
* Change uniquetitle to unusedtitle
* Fix a typo
@BurningTreeC I think this might have been a typo in your recent refactorings; if you look back at an old version such as c0c1b557eb/core/modules/widgets/reveal.js then there is no sign of this fallback.
